INIPRQVEMENT IN MOULD FOR CASTING SOLDER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it ma/y concern:

Be it known that I, JOHN FANN'ING, of Brooklyn, in thecounty of Kings, and State of New York, have invented and made a certain new and useful Improvements in Moulds for Casting Solder and ot-her metal into bars or pigs; and I do hereby declare the following to be a full, clear, and exact description ofthe said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a plan of said mould, complete;

Figure 2 is a cross-section of the same; and

Figure 3 is an endview, with the end-piece of the mould turned up, to give access tosad mould.

Similar marks of reference denote the same parts.

.In making moulds inwhich solder and other metals are usually cast into bars, ingots, or pigs,it is usual to engrave or otherwise form names, letters, numbers, or other characters in thebottom of the mould) whereby the article cast is designated, or its quality made known, andthe makers name also denoted. v 4

These moulds are very costly, and it is diiicult to make the characters clean-and handsome at the bottom of a mould, because ot' the depth of the same. Besidesthis, the characters being a part of the mould, necessitates the construction ot' a complete mould for any change of cha1acter,to,designate a different quality of metal, although the bar or ingot may be the same size and shape;

The present invention 'consists in a sliding plate, forming a movable bottom tothe mould, and in this the lett-ers or characters are formed.

This facilitates the construction of the monldby enabling the workman to engrave or form the letters much more easily than can be done at the bottom of the mould, and the plates being movable, the mould itself may be employed witlrdiii'erent plates, thus saving cost in the original construction ofthe mould, and

rendering it more useful, and lessening the number of moulds required. v

In the drawing the mould` is shown as made with a bottom portion, c, upon which are longitudinal bars b c d, and end portions c f, so as to produce two cavities, or moulds, for receiving the melted lead or other metal.

These moulds may be of any desired size or shape, and grouped together -in greater or less numbers.

The end-piece f is malle. movable, andthe mould is formed with dovetailed, or under-out grooves, .at the junction of the bottom and sides of the mould, so as to receive the movable bottom` plate h, that is slipped endwise into the said grooves, and contains, in or upon its upper surface, the letters or characters that are to heA produced in the bar, ingot, or pig, that is cast' iu said` mould.

The end-piece fbeiug movable, gives access for removing one ofthe plates, h, and introducing a different plate, as `occasion may require.

I` do not claim casting stereotype plates between a matrix and a dovetaled wooden block, as this has before. been done.

NVhat I claim, and desire to secure by Letters Patent, is I Forming the bottom of the mould with a recess, for

.receiving the movable bottom, that is slipped into place as set forth, and contains the letters or characters to be formed in casting upon the iugot or bar, substantially as set forth;

In witness whereof, I have hereunto set my signature, this 13th day of April, A. D. 1869.
